,gister @anni JOI-IN MURDOCK, OF JERSEYYCITY,

NEW JERSEY, ASSIGNOR TO JOHN SAVERYS SONS, OF NEW YORK CITY.

`Leners Patent No. 88,799, @ated April is, 1869.

To all whom it ma/y concemf Be it known that I, J OHN MURDOCK, of Jersey City, in the county of Hudson, and State of New Jersey, have invented and made a new and useful Improvement in Bird-Houses; and I do hereby declare the followingr to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein-L Figure l is a view, showing half of said bird-house in section, and the other half in elevation;

Figure 2 is a sectional plan at the line x a: and

Figure 3 is a vertical section at the line y y.

Similar marks of' reference `denote the same parts.

The object of this invention is to furnish aneat and durable bird-house, that is adapted to small birds, such as sparrows, and is perfectly safe from the attacks of cats, hawks, &c., and said house is constructed so that it can be easily opened for cleaning when desired.

In the drawing, c represents the basel of the birdhouse, which is concave, so as to be adapted to receiv ing the nest.

This lbase may have in the bottom a screw, b, by

means of which the house may be attached to the top of a post, or other convenient article.

The sides of the house are formed ofthe cylindrical portion c, united to the base a, by the screws d, and e `is a roof, or topkof an ornamental character, and projecting snciently to shed the rain.

In one side of the house is an opening, surrounded by a ange, f, said flange forming a protection around said opening, and within this opening is the movable shield g, 'having a base-dange, 2, and setting in front of the lugs 3 3, that are cast upon the inner angles of the opening, into which said shield is slipped.

The base-ange 2 causes any rain toA pass outside the flange f, and the shield gis of a height to allow sufficient opening for small birds to pass in over its lupper end; but this shield and the'lange f prevent cats or birds of prey from getting at the birds in the house. y

The shield and ange maybe applied on two or more sides of the bird-house, andthe interior portion of said house may be subdivided.

When the house is to be cleaned out, the shield g can be slipped up nntil above the lugs 3, and then turned around and taken cut. The 'reverse movement replaces the shield.

What I claim, and desire to secure by Letters Patent, is

The flange f and movable shield g, constructed as specified, and applied to the opening of the bird-honse, for the purposes set forth. p

In witness whereof, I have hereunto set my signature, this 27th day of February, A. D.a 1869.

. JOHN MURDOOK.
